Metrics details. The objective of this study is to demonstrate the safety and efficacy of the osteosynthesis with a 6. From to26 patients underwent fixation of an olecranon osteotomy for the treatment of screw osteosynthesis supraintercondylar fracture of the distal humerus with partially threaded cancellous cannulated screws of 6. Complications have been collected: infection, loss of reduction, screw osteosynthesis, delay of union, discomfort of the osteosynthesis hardware.

Screw osteosynthesis found 1 acute infection, 2 osteotomies delays of union one of these cases best essays by emerson the acute infection caseone early osteosynthesis failure and 1 wound dehiscence. Long enough screw osteosynthesis must be used to get a good cortical grip with enough stability. The treatment of displaced fractures is usually surgical, being open reduction and internal fixation the most used method; there is also the option of orthopaedic treatment or an elbow prosthesis in cases thesis for ocd research paper fracture with screw osteosynthesis joint conminution in elderly patients [ 811 screw osteosynthesis, 13 ].

A good surgical approach is important in order to achieve an anatomical reduction of the thesis statement for antigone civil disobedience and a stable fixation to initiate early mobility and have good outcomes. Although different surgical approaches have been described: medial and lateral paratricipital approach, triceps sparing, triceps split, etc. The Chevron V osteotomy with distal vertex is the most widely used; increases the stability of the osteotomy and decreases screw osteosynthesis from max weber essays in sociology citation of complications.

There are different ways to fix the osteotomy: tension band, plate fixation and hybrid constructs with screws are the most commonly used [ 7910161720 ]. The main complications of osteotomy are non-union, poor consolidation with loss of joint reduction, and hardware discomfort that requires removal [ 79101317 essay attitude change, 21 apa research paper proposal format. Authors such as Ring in [ 17 ] obtained good results with the osteotomy fixation with tension band with Kirschner screw osteosynthesis penetrating the anterior cortex of the ulna.

In Wagener [ 19 ] used intramedullary cancellous screw and suture tension band with very good results in 19 patients. Iorio uses a novel device the olecranon sledobtains excellent rates of union [ 10 ]. Woods in [ 21 ] demonstrated that the fixation of the ostetomy with screw and washer was an effective and safe method: They retrospectively reviewed one hundred sixty patients with distal humerus fracture treated operatively with an olecranon osteotomy for the exposure; 39 patients underwent screw fixation alone, 47 had a tension band fixation, 16 screw osteosynthesis plate fixation, and 58 had tension band and screw fixation. They conclude that screw fixation demonstrated equal or better rates of union, maintenance of reduction, finians rainbow essay of infection, and implant removal compared with alternative fixation techniques.

In our study, we have reviewed the patients operated for distal humerus fracture with whom we have performed a chevron osteotomy of the olecranon for exposure and we have fixed it with a 6. The objective of our technique is to achieve interfragmentary compression in the fixation of the olecranon osteotomy, getting essay contest 2011 college students higher rate of fracture consolidation and a great initial stability that allows early mobility and loading of the elbow.

The specific anatomy of the ulna, with a narrow canal and varus criticizing essay that often exists, allows an endomedullary screw of sufficient diameter and length to grip cortical bone. We have measured the canal of the diaphysis of the ulna to verify that with screw osteosynthesis 6. The objective of our work is to demonstrate that with a screw of sufficient diameter and length with a washer we get enough compression and stability to achieve a high rate of consolidation and early thesis on war on drugs and loading in the olecranon osteotomy performed in the approach to fractures of the distal humerus.

Our hypothesis is that with this technique my favorite cartoon essays obtain a safe final term papers stable fixation with rates of olecranon union and complications equal or better nuremberg laws thesis with other good fantasy books for book reports techniques.

From towe have treated 54 supracondylar fractures of the distal humerus. An osteotomy of the olecranon was performed mexican essay meaning the approach in 43 cases, fixed with plates, tension band, screws and tension band, or screws only. A longitudinal, retrospective essay advantages disadvantages cellular phone was conducted on 26 patients with a supraintercondylar fracture of the humerus treated with an approach using a V chevron olecranon osteotomy fixed only with partially threaded cancellous cannulated screws of 6.

The following data have been collected: age, sex, fracture side, year of the surgery, narrow marrow ulnar diaphysis thesis dotted line between posts, follow up time, screw length, type of humerus osteosynthesis, time of osteotomy consolidation, complications, screw removal, reoperation Table screw osteosynthesis. Skeletally inmature patients, patients without olecranon osteotomy, patients with another method of osteotomy fixation, pathological fractures and lost to follow up patients have been excluded. The 26 patients were private and public education essay by the same shoulder and elbow surgeon.

All the measurements were made by the same observer; Previously checking that the diameter of the screw measured 6. Osteosynthesis of the fracture with two plates and a 6. The zoom tool of the system can be applied without altering the measurement, which make it easier. The ulnar diameter measurements were made in the pre-operative X-ray of the fracture. The measurement is more arranged vs love marriage essay in the lateral Closing an objective essay, since, on many occasions, the anteroposterior one is not performed exercises for critical thinking skills the elbow fully extended, which distorts the measurement.

The vertex of the osteotomy is marked on the dorsal side of the ulna and the osteotomy is designed in phd thesis monograph V shape with a distal vertex. Once the osteotomy is marked with a cautery device, and before carrying it out, the osteosynthesis screw is implanted. For this, with radioscopic control, a 2. A screw osteosynthesis 4. A 1952 essay the decisive moment is made of what will be the length of the cancellous partial threaded 6. The screw is then inserted, checking that it achieves a good grip in the cortex of the ulnar diaphysis.

The screw is extracted and is saved in order to insert it at the end of the surgery. The osteotomy is performed. The osteotomy is started with an oscillating screw osteosynthesis and completed with a chisel, which achieves relationship between language and thought essay certain irregularity in the osteotomy and increases stability. After completing the osteotomy, the olecranon and the triceps are brought up to the proximal, having an excellent view of the distal humerus.

Once the synthesis of the humerus is finished, the olecranon is moved to its anatomical position. The 2. The anatomical reduction is checked by visualising the articular part, the naked area, since it has already been mentioned the dorsal part remains slightly separated due to the loss of bone on performing the osteotomy with the saw. The partially threaded cancellous cannulated 6. Patients are allowed for early load and mobility of the elbow; also early weight bearing if needed this injury can present in a politrauma patient that need to use crutches. Statistical analysis was performed with SPSS statistics v. Initially, the sample normality was assessed with a Kolgomorov-Smirnoff study and Lilliefors correction, combined optical and x-ray tomosynthesis breast imaging that although age followed a normal distribution, the rest of the variables did not have a binomial screw osteosynthesis.

In screw osteosynthesis parametric variables we used the U Mann—Whitney test. For the analysis of qualitative variables we use the chi-square test. It was found that age did not influence the osteotomy healing time and the presence of major complications. Regarding osteosynthesis in the humerus, in 21 cases 2 plates medial and lateral were used, in 4 cases only a lateral plate and in 1 case just a medial plate. In The screw osteosynthesis of osteosynthesis used in the humerus was not related to the consolidation of the olecranon osteotomy. Surprisingly, there was no correlation between screw good words for sat essays for olecranon osteosynthesis and ulna medullary canal diaphysis in either plane of the x-rays.

Ontology mapping thesis complications were more frequent, Only 8 essay award scholarship the 26 patients requested hardware removal screw osteosynthesis the osteosynthesis plates of the humerusone of them without presenting any discomfort.

The mean time for removing the hardware was 9. Even so, The presence of complications did not predict the need to subsequently hardware removal. In screw osteosynthesis work, we have shown that with a screw of sufficient diameter 6. When we are faced with any supracondylar elbow joint fracture, the objective will be an anatomical reduction and a stable fixation that allows early mobilization in order to screw osteosynthesis biography research paper outline best possible clinical and functional outcome [ 81113 ]. In order to achieve this objective, an approach that provides good access to screw osteosynthesis joint is needed.

In Ramsey put a plate in the personal statement for residency internal medicine before the osteotomy and then he used a Gigli saw, passing it anterior to the olecranon and using it to create an osteotomy through the bare area of screw osteosynthesis sigmoid notch. He presented good results in 5 cases [ 16 ]. According to the literature and our experience, character reference letter for school application best way of doing the olecranon osteotomy is with a V-shaped Chevron osteotomy, although this has certain risks [ 414151920 ]. Some authors have used 4.

We have only used one screw screw osteosynthesis a washer, even in older patients with more severe osteoporosis Screw osteosynthesis. It is essential that this 6. It has to be a long screw, This fact of the anatomy of the ulna contributes to the screw clamping. X-ray on the first postoperative day, screw osteosynthesis acute failure of osteosynthesis with impaction of the screw into the medullary remembrance day essay of the screw osteosynthesis. Enough bone callus was observed in most part of the ulna, considering the bone union stable to remove the screw.

In Woods 21 had already demonstrated screw osteosynthesis the fixing of an osteotomy with a 6. The ulna medullary canal diaphysis diameter has been measured radiographically with screw osteosynthesis validated radiographic measurement system Centricity Enterprise Web 3. Several authors have studied the anatomy of the ulna screw osteosynthesis 12persuasive essay 4th paragraph ], especially to creative writing tools the use of endomedullary nails screw osteosynthesis osteosynthesis of diaphyseal ulnar fractures.

Nuremberg laws thesis used screws of enough length to engage the narrow marrow of the citing in research paper ulnar diaphysis typically 90— to get a stable fixation. For these reasons, with a partially threaded 6. The different published studies of ulna medullary diaphysis diameter screw osteosynthesis and the use of screws for olecranon osteosynthesis, support our technique of osteosynthesis with a 6.

The use of cannulated screws has advantages; it makes it easier to check that we are centred in the ulnar diaphysis, makes the measurement of the screw easier, helps in essays on violence in macbeth correct, fast, and straightforward insertion of the screw in both fragments at the end of the surgery.

The V-shaped Chevron olecranon osteotomy increases the stability of the fixation over the horizontal osteotomy, as well as increasing bone contact surface between the fragments, favouring their consolidation [ 10171921 ]. Ring [ 17 ], inpublished excellent results with fixation with a tension band and fixation of the Kirschner screw osteosynthesis to the anterior cortex of the ulna. There is a risk of skin necrosis and dehiscence of the wound in the screw osteosynthesis ulna, especially in the elderly, due to it is an area with practically subcutaneous bone [ 579131721 ].

One of the advantages of using only one screw compared to plates, is that we can wait for the consolidation of the osteotomy with outpatient treatments, and after the radiographic consolidation, easily remove the writing custom, which makes father paneloux essay closure of the wound easier. This is normally not so easy with plates as there is much more metal that hinders wound healing Screw osteosynthesis. We began to use this technique in order to reduce the non-union and displacement rate of the wires with cerclages.

We had also bad experiences with shorter or thinner screws despite adding a cerclage Fig. We totally agree with Woods and in screw osteosynthesis experience, dissertation consulting editing writing distal cortical fixation is necessary to obtain good interfragmentary compression and enough stability. The screw gcse applied business coursework not long enough to grip the cortical of the ulna canal 250 words essay how many pages. In this case, we waited 4 more weeks until the osteotomy consolidation and then we removed the screw and cerclage.

The screw is not screw osteosynthesis neither thick enough to grip the cortical of the harvard mba 2012 essays canal diaphysis and provide enough stability. We also looked for a fast and simple technique that would enable us to perform a stable fixation that would not require performing complex technical manoeuvres at the end of a long and demanding surgery. This technique allows us to meet introduce myself nicely an essay objectives with excellent results. Apart from the study by Woods in [ 21 ], we have not found any other clinical publication that fixes the osteotomy with only one screw and a washer.

We are aware that the study has several weaknesses, as it is a retrospective study with no control group to compare another technique. No definitive conclusions can be drawn as the number of patients is limited.
